MACHINE FOR FEEDING, OPENING, AND MlXlNG WOOL.

SPECIFICATION forming part of Letters Patent No. 323,523, dated August 4,1885.

Application filed November 3, 1884. (No model) T 0 all whom it may concern.-

Be it known that I, STEPHEN R. PARK- HURs'r, of Montclair, in the county of Essex and State of New Jersey, have invented an Improvement in Machines for Feeding, Opening, and Mixing \Vool, of which the following is a specification.

The object of this invention is to feed wool with uniformity and automatically into an opening and mixing machine, that removes burrs and foreign substances, and delivers the material in a form adapted to be supplied to other woolen machinery, such as the carding and roving machines, so as to dispense with the picking and mixing machines heretofore made use of, and thereby dispense with several of the operations heretofore usually employed, and prevent the injury to and loss of wool heretofore experienced, especially in the picker-room. I

In the drawings, Figure 1 shows a vertical sect-ion of a burring machine containing my improvements. Fig. 2 is a diagram of the belt and gear connections by which the respective parts may be driven, and Fig. 3 is a sectional plan of one end of the feeding-hopper.

The toothed cylinder B, upon the shaft B, is driven by competent power in the direction of the arrow, and above the same, between the frames 3" of the machine is a hopper, A, formed of a shell, preferably of metal, and about three-quarters of a cylinder. A are ends to this hopper, and A are pivots or gudgeons upon which the hopper receives an oscillating motion from the revolving shaft b. For this purpose an eccentric on the shaft and a rod, L, to one end of the hopper may be employed; or there may be two eccentrics and rods, one at each end of the hopper. In the bottom of this hopper, and directly over the top of the toothed cylinder B, is a slot running longitudinally of the cylinder B, and at one edge of this slot there is a comb, c, and be neath the hopper A, and between the same and the cylinder B, there is a stationary bar, 0.

\Vhen the machine is in use, the wool is thrown in mass into the hopper A, and spread out with moderate uniformity, and the oscillating motion of the hopper forms the wool 5 into a long roll parallel to the axis of the hopper, and resting in the bottom thereof, and the teeth of the cylinder B catch into and draw the wool through the opening in the bottom ofthe hopper, and as saidhopper vibrates, the com b-teeth at the edge of the opening enter the locks of wool and hold the same back as the lock is opened by the drawing action of the teeth of such cylinder B, and as the comb draws back over the stationary bar 0 the latter acts as a stripper to clean the wool out of the comb, so that the said wool may be drawn along by the teeth of B, and spread with uniformity upon the said cylinder B, and passed to the opening, cleaning, carding, or mixing appliances, and when the wool in different colors is thrown into the hopper the same is mixed in forming the roll, and it is taken off by the said cylinder B, and the different colors are delivered from such cylinder B with uni formity.

In order to separate burrs and foreign sub stances I make use of a stripper or guard, G, that revolves in the direction indicated, and more thoroughly opens and spreads the locks of wool upon the teeth of the cylinder B, as well as knocking out the burrs.

I preferably employ a shell of sheet metal at c to prevent the locks of wool falling oil the cylinder B.

The wool may be removed from the toothed cylinder B by acylinder having teeth or card clothing, as indicated by the dotted line D; but Iprefer to use the revolving brush 1), that re moves the locks of wool from D and impales them upon the teeth of the rollers E E, which rollers are similar to the feed-rollers shown in my Patent No. 238,709. The teeth of these rollers E F aid in opening the locks of wool, and the brush as it passes by the wool upon the teeth still further opens the locks and brushes out impurities.

I find it preferable that the relative speed of the parts should be regulated, so that while the surface of the toothed cylinder B moves a distance of one, the ends of the brushes 1) should move a distance of about six, and the fecd-rollcrs a distance of about four.

The toothed cylinders G and H are revolved in the directions indicated by the arrows, and while the surfaces of the aforesaid parts are moving the distance named the surface of cylinder G should move about a distance of eight, and the surface of cylinderHa distance of about four. The result of these movements is that the wool is opened by a comparatively rapid movement of the teeth of cylinder G, while the locks are held between the rollers E and F; but the directions of motion are such that the teeth of the cylinder G draw the wool entirely out of and from between the teeth of the rollers E E, and the teeth of the cylinder H hold back the locks and open the same, because the teeth of the cylinder G are moving at a greater speed.

The delivery-cylinder I is preferably armed with wire teeth, usually straight, similar to the teeth upon revolving brushes, and these act from heel to point of the respective teeth on the cylinders G and H, and remove all the wool, and at the same time open the said wool still further.

The wool may be thrown off the brushblower I by the action of the atmosphere and centrifugal force, in which case the trunk (shown by dotted lines at I) may be used to convey the wool to a room; but I prefer to use a doffer-cylinder, N, and a comb or vibrator, N, for delivering the wool in the form of a bat or a sliver, as desired. These parts N N being of ordinary character and well known do not require furtherdescription; but I have shown a bent lever, N, with a connecting-rod to a crank-pin on the shaft of the cylinder H, and a connecting-rod to the doffercomb to move the same.

I also employ a stripper or guard, M, to still further remove foreign substances by acting against the wool while upon the cylinder G.

' It will be seen by this machine the rough or crude wool is by one operation opened, cleaned, and delivered in the form of a bat ready for any of the ordinary operations of carding, &c., thus dispensing with the ordinary mixingpicker, and the lint-room connected with the same.

In the diagram Fig. 2, the driving-shaft a is shown as connected by pulleys and a belt, 2, to the shaft 2), and from this the belt 3 drives a pinion, 4, that gives motion to the gearwheel 5 on the shaft B of the cylinder B. The belt 6 drives the roller F, and this and the roller E are geared together. The belt 7 from a drives the brush 1). The bolts 8 and 9 actuate the strippers G and M, respectively. The

shafts of the toothed cylinders G H are geared together at 11 12, and the shaft of the cylinder His driven by a belt, 14:, and pulley. The shaft of the brush I is driven by a belt, 16, and pulley. This diagram illustrates the connections, and I remark that the gears and pulleys are placed some at one side of the machine and some at the other side.

I claim as my invention 1. The combination,with arevolvingtoothed cylinder, of a feeding-hopper having a longitudinal opening in the bottom portion above the toothed cylinder, pivots to support the hopper, and a crank or equivalent mechanism for giving to the hopper an oscillating motion, and a comb fixed to the hopper at one side of the longitudinal opening, substantially as set forth.

2. The combination,witharevolving toothed cylinder, of a feeding-hopper having a longitudinal opening in the bottom, mechanism, substantially as specified, for moving the hopper transversely to the toothed cylinder, a comb upon the hopper at the longitudinal opening, and a stationary guard between the hopper and the cylinder, substantially as set forth.

3. The combination,with a revolving toothed cylinder, of a feeding-hopper having a longitudinal opening over the toothed cylinder, means for moving the hopper across above the toothed cylinder, and a revolving stripper acting to separate the burrs, substantially as set forth.

4. The combination, with a revolving toothed cylinder, of a feeding-hopper having a longitudinal opening over the toothed cylinder, teeth upon the hopper at the opening, a brush to remove the wool from the cylinder, the toothed cylinders F E G, and delivering-cylinder I, substantially as set forth.

5. The combination, with the cylinder 13, stripper O, and the slotted oscillating hopper A, of the toothedcylinders G H, the toothed cylinders between the cylinder B and the cylinder G, the delivery-cylinder I, the doffercylinder N, and comb and belts and pulleys or gearing to revolve the respective cylinders, substantially as set forth.
